The Rays recalled Rasmussen from Triple-A Durham on Thursday, Adam Berry of MLB.com reports.
Though he was optioned to Triple-A on Sunday, Rasmussen is eligible to rejoin the big club early since the Rays placed a player on the injured list (shortstop Taylor Walls) in a corresponding move. Rasmussen, who was acquired from the Brewers in May in the trade that sent Willy Adames to Milwaukee, was impressive in his Rays debut June 19, striking out four Mariners over 1.2 perfect innings in relief.
